Folding knife made according to specifications requested by the Italian Army unit 185th RAO (Regiment for Target Acquisition) and currently in service with the same unit. The service version differs from the civilian one only by the complete absence of writings or logos on the blade.
HISTORICAL NOTES ON THE UNIT:
The 185th RAO of the "Folgore" is a unit with ancient traditions, yet relatively new in its current form. It was established on 3 April 2000 following the reorganization of the 185th Paratroopers Artillery Regiment. Based in Livorno, it is an atypical artillery unit currently included within the Special Forces framework.
Composed entirely of volunteer personnel, the 185th RAO selects its members through physical tests and a qualification course structured in modules of increasing difficulty. The tasks assigned to RAO operators are numerous and highly sensitive: they involve gathering information on enemy targets and relaying it to command. More generally, this can be described as reconnaissance in sensitive areas.
"It is therefore clear," the Army emphasizes, "that the activity of the acquisition operator takes place mainly in hostile territory, in small self-sufficient teams operating in isolation."
RAO paratroopers are specialists in infiltration and exfiltration techniques and are able to operate in the field for up to 8–10 days without external resupply. They know how to avoid capture, escape and evade from enemy-controlled areas and, above all, how to identify, define and assess strategically relevant targets. Since 2002, the year of its reorganization, detachments of the 185th Regiment have operated in all major operational theaters: from the Balkans to Afghanistan and Iraq. In these areas they mainly carry out medium- and long-range reconnaissance and surveillance activities within the area of responsibility of the Italian contingent.

ExtremaRatio - 185° RAO - 2018 Version - heavy folding knife
New version 2018 with improved grip: uses the same handle as the RAO II model
Folding knife made to specific requests of the Italian Army department 185 ° RAO (Regiment Acquisition Objectives) and currently supplied to the homonymous department. The supplied knife differs from the civil one only because of the total lack of writing or logos on the blade.
HISTORICAL SUMS ON THE DEPARTMENT:
The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.
RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of responsibility of the Italian contingent.

ExtremaRatio - BFK Zero Folgore - Stonewashed N690Co & Black Anticorodal - knife
The BFK Zero FOLGORE is an operational EDC project developed in collaboration with the “Folgore” Parachute Brigade, designed for continuous professional use where there is no room for error and every component must perform predictably.
The 3mm N690Co stainless steel blade is engineered to offer a true balance between edge retention, durability, and control, without unnecessary extremes. It features a geometry geared toward intensive daily use, designed to perform rather than be preserved. The construction combines an aluminum handle with steel liners, creating a rigid frame with tight tolerances and consistent mechanical response even under stress.
The Crossbar Lock system ensures safety and reliability at every stage of operation, while maintaining fully ambidextrous handling. Internal bearings ensure a smooth, repeatable opening action, free of jamming, designed to feel natural even without active attention.
The ergonomics are designed for extended carry: the compact profile reduces bulk without compromising the grip, while the ambidextrous clip allows for discreet and customizable carry. The weight remains low for the category, with a balanced distribution that does not feel fragile.
The BFK Zero FOLGORE is a military folding knife conceived as a professional everyday carry tool. It is not designed to be displayed, but to be used. Compact, reliable, efficient
